With Maven 2.0.8, model.uri was correctly mapped to /Users/sarbogast/dev/myapp/src/main/uml/myapp.xmi
But with Maven 2.0.9, now it's mapped to /Users/sarbogast/dev/myapp/Users/sarbogast/dev/myapp/src/main/uml/myapp.xmi, which is not good at all.

I have attached a test project that builds with Maven 2.0.8 but not with Maven 2.0.9.
It's not the simplest project ever but it's a real AndroMDA skeleton project.
All the configuration is in mda/pom.xml
